HIFU (High Intensity Focused Ultrasound) device is a device that treats patients by using high heat generated from focus when burning high intensity ultrasound energy to burn tissues.

Focusing ultrasound waves about 100,000 times stronger than the ultrasound intensity used for diagnosis generates heat at the focal spot, which is similar to the heat generated at the focal spot when sun light is collected by the convex lens. Ultrasound itself is harmless to the human body and heat is generated only at the focal point where the ultrasound is concentrated, so it is possible to treat lesions in the body without the need for general anesthesia without using a knife or needle.

The structure of the HIFU apparatus can be broadly divided into a base, a treatment head, and a support structure installed on the base to support the treatment head.

The treatment head includes a transducer and a container for converting electrical energy into ultrasonic energy. The container is attached to the treatment head while surrounding the transducer as a fluid membrane, and serves to contain the fluid that cools the high heat generated when ultrasonic waves are emitted from the transducer.

First, the fluid supply apparatus 10 according to the embodiment of the present invention includes a treatment head 20, a circulation path 30, a sensor, a pump, and a controller 50.

Treatment head 20 is installed in the body 24, the body 24, the transducer 23 for transmitting and receiving ultrasound, the container surrounding the transducer 23 is attached to one side of the body 24 (22).

The transducer 23 may include a piezoelectric element, and is a device capable of converting electrical energy into vibration energy through the operation of the piezoelectric element. One embodiment of the transducer 23 may be manufactured by attaching an acoustic matching layer to the front part of the piezoelectric element and attaching a sound absorbing layer to the rear part. A lens may be formed on the front portion of the acoustic matching layer. Ultrasonic waves are generated by piezoelectric elements, and ultrasonic waves generated from piezoelectric elements may be irradiated through the lens.

The treatment head 20 includes a fluid space 29 that can contain the first fluid 35. The fluid space 29 is surrounded by the body 24 and the container 22.

The first fluid 35 serves as a medium of ultrasonic waves. That is, the ultrasonic wave irradiated from the transducer 23 may be smoothly transmitted to the object to be treated through the first fluid 35. In addition, the first fluid 35 serves as a cooling water for suppressing the temperature rise due to the heat generated during the irradiation of the ultrasonic waves by the transducer 23.

The first fluid 35 may be water, depending on the embodiment.

The circulation path 30 includes a fluid space 29 on the treatment head 20, and is connected to each of the first inlet 25 and the first outlet 27 of the treatment head 20. In the treatment head 20, the first inlet 25 and the first outlet 27 may be formed in the body 24 according to an exemplary embodiment.

The first fluid 35 flows through the circulation path 30, enters the fluid space 29 through the first inlet 25, and flows out of the fluid space 29 through the first outlet 27.

The sensor measures the pressure of the first fluid 35 flowing through the circulation path 30 and transmits a signal having pressure information to the controller 50. The control unit 50 may be electrically connected to a sensor or a pump according to an embodiment. The control unit 50 may receive a signal related to the pressure of the first fluid 35 from the sensor to operate or stop the pump.

When the pressure of the fluid space 29 reaches a predetermined value while supplying the first fluid 35 to the fluid space 29, the sensor is operated to interrupt the operation of the pump to stop the supply of the first fluid 35. .

In addition, when the pressure of the fluid space 29 reaches a predetermined value while the first fluid 35 is drained from the fluid space 29, the sensor operates to block the operation of the pump to drain the drainage of the first fluid 35. Block it.

The pump may include a first pump 43 and a second pump 44 according to an embodiment. The first pump 43 serves to introduce the first fluid 35 into the treatment, and the second pump 44 serves to outflow the first fluid 35 from the treatment.

The sensor does not necessarily need to be installed in the fluid space 29, and it is sufficient to be installed at a position where the pressure of the fluid space 29 is known on the circulation path 30.

The sensor may include a first sensor 41 and a second sensor 42 according to an embodiment. The first sensor 41 may be installed between the first inlet 25 and the first pump 43 on the circulation path 30, and the second sensor 42 may be the first outlet 27 and the second pump. It may be provided between the 44.

The controller 50 may control the first or second pump 44 by receiving a signal output from the first or second sensor 42.

According to an embodiment, when the first fluid 35 flows into the treatment head 20, the controller 50 receives a signal indicating a pressure value higher than a preset value from the first sensor 41. The operation of stopping the operation of the first pump 43 may be controlled.

In addition, when the first fluid 35 flows out of the treatment head 20, the controller 50 may output a signal indicating a pressure value lower than a preset value from the second sensor 42. If received, it can be controlled to stop the operation of the second pump (44).

The first pump 43 and the second pump 44 do not necessarily operate at the same time, and may operate independently of each other as necessary.

One of several features of the fluid supply apparatus 10 according to the embodiment of the present invention is that the first fluid 35 is automatically supplied and drained to the treatment head 20. That is, since the supply and drainage are automatically performed by the sensor and the controller 50, the user of the ultrasound therapy apparatus does not need to manually supply the first fluid 35. The fact that the first fluid 35 is automatically supplied and drained has the advantage of quickly filling the appropriate amount of the first fluid 35 with the treatment head 20, and it is convenient to use the ultrasonic treatment device. It provides an advantage, which shortens the time taken for the preparation of the treatment.

Fluid supply method according to an embodiment of the present invention may include a step (S100) for circulating the first fluid 35 on the circulation path 30 is installed by the treatment head 20 by operating the pump. In addition, the method may include a step (S200) of blocking an outlet of the first fluid 35 installed in the treatment head 20. In addition, the sensor may include the step of sensing the pressure value of the first fluid 35 and transmits it to the control unit 50 (S300). On the other hand, the control unit 50 may include the step of stopping the operation of the pump (S400) when the pressure of the first fluid 35 reaches the predetermined value by analyzing the sensed information.

The fluid supply method according to an embodiment of the present invention will be described in more detail. First, the controller 50 opens both the first inlet 25 and the first outlet 27 so that the first fluid 35 circulates on the circulation path 30 (S100). This is because if only the first inlet 25 is opened and the first fluid 35 is introduced into the treatment head 20 while the first outlet 27 is blocked, the air, which has preemptively occupied the interior of the treatment head 20. This is because the pressure of the first fluid 35 is increased before the treatment head 20 is filled with the appropriate amount of the first fluid 35 so that the sensor can stop the operation of the first pump 43.

Next, the controller 50 blocks the first outlet 27 and fills the first fluid 35 in the fluid space 29 (S200). When the appropriate amount of the first fluid 35 is filled in the fluid space 29, the first sensor 41 senses it and transmits it to the controller 50 (S300), and the controller 50 receives the first sensor 41. When it is determined that the pressure of the first fluid 35 is higher than the predetermined pressure value by the signal received from the), it is possible to stop the operation of the first pump 43 to block the inflow of the first fluid 35 (S400).

If the pressure of the fluid space 29 is higher than the predetermined pressure, the second sensor 42 and the controller 50 may operate the second pump 44 to allow drainage. In addition, if the pressure of the fluid space 29 is lower than the predetermined pressure, the controller 50 may stop the operation of the second pump 44.

The method of controlling the first or second pump 44 by the controller 50 based on the signal received from the first or second sensor 42 is not limited to the above-described embodiment, but various other configurations are possible.

One of the features of the present invention is that a separate cooling device for the first fluid 35 is provided in the treatment head 20. In addition, one of the features of the present invention is that the cooling device operates in conjunction with the fluid supply device (10).

In the fluid supply apparatus 10 according to another embodiment of the present invention, the treatment head 20 may be formed with a second inlet 26 and a second outlet 28, the second fluid pipe ( 21). The second fluid pipe 21 may be provided in the fluid space 29. One end of the second fluid pipe 21 may be connected to the second inlet 26, and the other end thereof may be connected to the second outlet 28. The second fluid pipe 21 is preferably installed between the transducer 23 and the container 22 installed inside the treatment head 20. Since the transducer 23 mainly generates heat at the portion to which the ultrasonic waves are irradiated, the front of the surface to which the ultrasonic waves are irradiated has the highest temperature. Therefore, it is preferable to install the second fluid pipe 21, which is a cooling device, in front of the portion where the temperature of the first fluid 35 rises first rather than the rear or side of the transducer 23 in view of the efficiency of the cooling action. . In this case, the second fluid pipe 21 is preferably disposed at a position not blocking the ultrasonic traveling path on the fluid space 29. That is, the ultrasonic wave of the transducer 23 is preferably installed in front of the surface to be irradiated, and is formed along the edge of the surface to which the ultrasonic wave is irradiated.

In the above-described fluid supply device 10, the circulation path 30 is the first circulation pipe 31 and the second circulation in the section between the treatment head 20 and the first pump 43 according to the embodiment It may include a conduit 32. In addition, the circulation path 30 may include a third circulation pipe 33 and a fourth circulation pipe 34 in a section between the treatment head 20 and the second pump 44. The fluid distributor 45 may be installed at the start points of the first and second circulation pipes 32, and the fluid confluencer 46 may be installed at the end points of the third and fourth circulation pipes 34. The fluid distributor 45 may be a three-way solenoid valve, depending on the embodiment. The fluid distributor 45 may be electrically connected to the controller 50. The control unit 50 introduces the first fluid 35 into the treatment head 20 through the first circulation conduit 31 or into the treatment head 20 through the second circulation conduit 32. It can also be introduced. According to an embodiment, the first sensor 41 may be installed on the first circulation pipe 31, and the second sensor 42 may be installed on the third circulation pipe 33. In the present embodiment, the second circulation pipe 32 is connected to the second inlet 26, and the fourth circulation pipe 34 is connected to the second outlet 28. According to the embodiment, the fluid storage tank 60 may be additionally installed between the first pump 43 and the second pump 44 on the circulation path 30. In addition, the fluid reservoir 60 may further include a cooler capable of cooling the first fluid 35.

An operation relationship of the cooling device included in the fluid supply device 10 according to the embodiment of the present invention will be described.

The fluid flowing in the circulation path 30 includes a first fluid 35 and a second fluid 36. The first fluid 35 refers to a fluid circulating through the circulation path 30 through the first circulation pipe 31, the fluid space 29, and the third circulation pipe 33, and the second fluid 36 is a second fluid. The fluid circulates through the circulation path 30 through the circulation pipe 32, the second fluid pipe 21, and the fourth circulation pipe 34. For convenience of explanation, the circulation path 30 including the first circulation pipe 31, the fluid space 29, and the third circulation pipe 33 is called a first path, and the second circulation pipe 32, for the second fluid The circulation path 30 including the pipe 21 and the fourth circulation pipe 34 is called a second path. The first fluid 35 then circulates through the first path and the second fluid 36 circulates through the second path.

When the treatment head 20 performs the treatment, the fluid distributor 45 is operated so that the fluid flowing through the first path flows through the second path. While the treatment is being performed, the first fluid 35 should not circulate in the fluid space 29. This is because the irradiation of the ultrasound is not made smoothly and the treatment may be difficult. Therefore, the first fluid 35 must remain in the fluid space 29 while the treatment is being performed. However, since the transducer 23 generates heat while irradiating ultrasonic waves, the temperature of the first fluid 35 staying without circulation increases. This increase in temperature can damage the transducer 23 and can burn the patient being the patient. Since the treatment must be stopped to lower the elevated temperature inside the container 22, the treatment time increases.

The fluid supply device 10 equipped with the cooling device according to the embodiment of the present invention is configured to continuously circulate the second fluid 36 through the second fluid pipe 21 while the treatment is performed. ) And heat exchange between the first fluid 35 staying in the fluid space 29 can suppress or slow down the temperature rise of the first fluid 35. This, in turn, allows the treatment to be carried out continuously, thereby increasing the treatment time. According to an embodiment, the second fluid 36 may flow through the second fluid pipe 21 after being cooled by the cooler in the fluid reservoir 60. In this case, since the temperature difference between the second fluid 36 and the first fluid 35 is large, the cooling effect of the first fluid 35 is further increased.

In some embodiments, the fluid reservoir 60 may further include an air remover for removing air from the first fluid 35. If bubbles are present in the first fluid 35, ultrasonic waves may be reflected to damage the transducer 23. Therefore, it is necessary to remove the air of the fluid circulating through the circulation path 30 through the air remover.

According to the exemplary embodiment, the fluid supply device 10 may further include a fifth circulation pipe connecting the first circulation pipe 31 and the fluid storage tank 60. A relief valve 70 may be installed on the fifth circulation passage. The relief valve 70 is a valve or a safety valve that ejects pressure, and when the pressure of the first fluid 35 on the first circulation line 31 reaches or exceeds a predetermined pressure, the relief valve 70 ejects the treatment head to the fifth circulation line. 20) to protect. Treatment head 20 is an expensive equipment, it is economical to be protected by a simple structure, such as a relief valve (70).

HIFU treatment head 20 according to an embodiment of the present invention is provided with a container 22 at one end, the body having a second inlet 26 and the second outlet 28 for the second fluid (36) And (24).

In addition, the body 24 may include a transducer 23 installed inside the body and irradiates ultrasonic waves.

And, the second fluid pipe 21 may be included. The second fluid pipe 21 may be disposed at a position not blocking the ultrasonic traveling path on the fluid space 29 between the container 22 and the transducer 23. According to an embodiment, the second fluid pipe 21 may be installed in front of the surface to which the ultrasonic wave of the transducer 23 is irradiated, and may be formed along the edge of the surface to which the ultrasonic wave is irradiated. According to the exemplary embodiment, the second fluid pipe 21 may be formed in the shape of irregularities such that the area in contact with the first fluid 35 is increased. One end of the second fluid pipe 21 may be connected to the second inlet 26, and the other end thereof may be connected to the second outlet 28.

The body 24 may further include a first inlet 25 and a first outlet 27 for the first fluid 35.

In some embodiments, the first fluid 35 and the second fluid 36 may be water. In addition, the second fluid 36 has a lower temperature than the first fluid 35.

On the other hand, an embodiment of the ultrasonic medical device according to the present invention is a medical device that may include the fluid supply device 10 or the treatment head 20 described above. Any medical device to which the fluid supply device 10 or the treatment head 20 of the above-described embodiment can be applied may be used. Since such an ultrasonic medical device itself is much known in the art, a detailed description thereof will be omitted.

The treatment head 20 with the cooling device described above is particularly advantageous when the container 22 containing the medium is small. In other words, if the container 22 is small, a small amount of medium may enter, so that the temperature of the medium increases rapidly due to the heat generation of the transducer 23. In the case of the treatment head 20 to which the small container is applied, the fluid space 29 If the above-mentioned cooling apparatus is provided, it is advantageous to be able to effectively suppress the temperature rise.

Although the detailed description of the present invention described above has been described with reference to preferred embodiments of the present invention, those skilled in the art or those skilled in the art will have the idea of the present invention described in the claims to be described later.
